    Hints for effective data collection Getting better samples How does the CBR 2™ sonic motion detector work? Understanding how a sonic motion detector works can help you get better data plots. The motion detector sends out an ultrasonic pulse and then measures how long it takes for that pulse to return after bouncing off the closest object.

    If any of these values map to a different pixel, the expected flat line may show occasional blips. The Velocity-Time plot may appear even more jagged, because the change in distance between any two points over time is, by definition, velocity. © 1997, 2004, 2006 T CBR 2™ S EXAS NSTRUMENTS NCORPORATED...
